Description

APPARATUS FOR THE DISPOSAL OF NUCLEAR WASTE, METHOD FOR THE MANUFACTURE AND INSTALLATION OF THE SAME FIELD OF THE INVENTION The present invention relates to an apparatus for disposing nuclear waste, and to a method for the manufacture thereof. More particularly, the present invention relates to a nuclear waste disposal apparatus and a method for the manufacture thereof, the apparatus has a perfect shield for radiation and a structure of sealing and structural safety because the nuclear waste generated from Nuclear power plants or atomic energy research institutes are put inside ring-shaped elastic bodies such as waste tires, nuclear waste is covered with reinforced concrete of ultra high strength to protect the nuclear waste, and structural steel It is installed in the concrete in the vertical direction and the horizontal direction in order to increase the durability of the apparatus against a heavy load and natural disasters such as earthquakes.

BACKGROUND OF THE INVENTION In general, nuclear energy is an energy produced when the state of an atomic nucleus is changed, REF.:184932 and it is also called atomic energy or nuclear energy. A nuclear power plant artificially produces such nuclear energy by artificially transforming an atomic nucleus of a material. The method for the production of nuclear energy is classified in a nuclear fission, in which an atomic nucleus of a heavy material such as uranium or plutonium is fissioned in series, and a nuclear fusion, in which the atomic nuclei of a light material , such as heavy hydrogen, are fused. The early stages of atomic bombs and atomic reactors used nuclear fission, and hydrogen bombs use nuclear fusion. The term "nuclear waste" means the by-products produced when nuclear power plants or nuclear power research institutes are operated. Nuclear waste is highly radioactive, because it is a by-product generated during nuclear fission in a nuclear reactor of a nuclear power plant and continuously creates heat even after the completion of nuclear fission. That is, nuclear waste is nuclear fuel used and is classified as high-level waste, which means the remnants after the nuclear fusion of nuclear fuel, other than uranium and plutonium, which can be reused, and low-level waste. level and level intermediate, which means the remnants after the processing of liquid waste, and the items used by operators to handle high-level waste, such as clothes, gloves and other components. Since nuclear waste contains a large amount of radioactive material, and such radioactive material can spread rapidly into the environment through wind and water, even if the nuclear waste is released into the air for only a few seconds, it is fatal for humans. This has led to endless discussions regarding the disposal of nuclear waste because it can not be guaranteed that nuclear waste stored and sealed in a disposal container is safe when stored deep underground. In Korea, nuclear waste is divided by light water reactor waste and heavy water reactor waste. The nuclear waste is stored in water as soon as it is discharged from a nuclear reactor, in order to reduce the amount of heat and radiation level. Nuclear waste cooled in water for one year has a caloric value of approximately 12 kw / tonU and a radiation amount of 2700 kCi / tonU, but these values represent reductions of up to approximately 3 / 1,000 times the initial values thereof, in comparison to immediately after being discharged from the nuclear reactor. Since radiation from nuclear waste can not be extinguished by the chemical reactionThere is no solution to treat nuclear waste, but to wait for the radioactivity of nuclear waste to decrease naturally. Consequently, it is the task of current societies to create a method to permanently and safely store nuclear waste. In order to solve this problem, most countries adopt a method to bury nuclear waste deep beneath the ground, after placing it in a container treated by a predetermined method and sealing it. That is, in order to more safely handle nuclear waste, solid nuclear waste is pressed at ultra high pressure and stored in a drum. The liquid nuclear waste is processed according to the following sequence: vaporization of the liquid nuclear waste in order to reduce the volume thereof, the solidification of the liquid nuclear waste by mixing the liquid nuclear waste with cement, and placing the solidified waste in a drum, and sealing the drum. The drum is stored in a storage tank. Gaseous nuclear waste stored in a sealed tank until the Its radiation degree has decreased to a predetermined level and then it is allowed to escape into the air through a high efficiency particle filter. In Korea, 12 nuclear power plants have been operating since 1997, since the first nuclear power plant was built in 1978. Therefore, by May 1997, 48,436 drums, 200 liters per drum, of nuclear waste of intermediate level and low were accumulated and stored. Nuclear waste is temporarily stored at the sites of nuclear power plants, but current facilities for storing nuclear waste will be filled to full capacity by 2008. In addition, it is expected that the amount of nuclear waste will be increased further, since that medical institutes and industries are increasingly using radioactive isotopes and new nuclear power plants are being built. Consequently, although nuclear waste is currently stored temporarily and safely in storage tanks at nuclear power plants, problems with nuclear waste are emerging from the viewpoints of limited storage capacity and storage site management . Nuclear waste was first generated for military purposes such as nuclear tests, but nowadays the amount of nuclear waste generated by nuclear Civil nuclear power plants have surpassed that of nuclear waste generated from military use. In addition, the cumulative total amount of nuclear waste is increasing sharply. On the other hand, the dumping at sea of nuclear waste was banned worldwide by a treaty signed at the London Convention in 1996. However, the London Convention treaty does not prohibit all nuclear waste, but allows discharge into the sea of seven articles. This treaty was made in order to avoid marine water contamination that can be caused by the oxidation of steel vessels that store nuclear waste, discharged into the sea. Consequently, in order to solve that problem, the steel containers kept the nuclear waste in these were discharged into the sea, packed in steel containers. However, the steel container also has the problem of causing seawater contamination because it is also oxidized by seawater. As a result, in most countries, a method for storing nuclear waste and a method for constructing facilities to safely bury nuclear waste remains an unsolved problem. As a result, it is an urgent need to solve the problems to dispose of safely and store nuclear waste for all countries worldwide.

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, the features and other advantages of the present invention will be more apparent from the following description with reference to the appended figures. Figure 1 is a perspective view illustrating a nuclear waste disposal apparatus according to an embodiment of the present invention. Fig. 2 is an exploded perspective view illustrating a nuclear waste disposal apparatus according to an embodiment of the present invention, and Fig. 3 is a flow diagram showing a method for manufacturing an apparatus for disposing of nuclear waste. nuclear waste according to the present invention. With reference to Figures 1 to 3, the nuclear waste disposal apparatus 1 according to the present invention comprises a plurality of elastic bodies 10, containers 30 for storing nuclear waste therein, and reinforced concrete 40 of high strength . The elastic body 10 is made of rubber, and has a ring shape with a central circular hole from side to side 11. According to this embodiment, the elastic body 10 has a central circular hole 11 in the center thereof, but can alternatively have a hole 11 from side to side polygonal instead of the circular hole 11. Furthermore, according to this embodiment, the elastic body 10 is a piece of rubber in shape of ring, but may be general tires or waste tires having a ring shape and a central hole 11. The elastic body 10 may be made of synthetic resin containing rubber. In the case, in which the elastic body 10 is implemented as a waste tire, which can be used by vehicles and whose life span is finished, the waste tires used by trucks or buses of large trucks are preferable to those used on general automobiles, because the internal diameter and size are larger and the durability of them is greater. That is, the waste tires used by large-sized trucks or buses, which have high rigidity, durability and impact absorptivity, and which are required to withstand heavy load and the weight of the vehicle itself at high speed, are more suitable for the elastic body 10, so that the containers 30 held in the elastic body 10 can better withstand external pressure and impacts.

The containers 30 are stacked in a space defined by the central hole 11 from side to side, of the elastic bodies 10, which are stacked, and the containers 30 store nuclear waste generated in the nuclear power plants and in the research institutes. The internal diameter and the size of the elastic body 10 surrounding the container 30 are determined according to the diameter of the container 30. Furthermore, three or more containers 30 are generally stacked in the space defined by the central holes 11 of the stacked elastic bodies. 10, but the number of stacked containers 30 may be less than or greater than three. The height and number of the elastic bodies 10 that are stacked in the vertical direction preferably correspond to the height and number of containers 30 installed in the internal space thereof. The reinforced concrete 40 of ultra high strength is injected into the space defined by the central holes 11 of the elastic bodies 10, and is cured therein. Concrete 40 can be special marine concrete that has high strength. According to this embodiment, the concrete applied in the internal space defined by the central holes 11 of the elastic bodies 10 stacked in the vertical direction and cured in them, is reinforced concrete 40 of high resistance or reinforced concrete of high resistance for use at sea. However, any concrete ingredients can be used if the concrete can protect and seal the containers 30 installed in the space 11 defined by the central holes 11 of the elastic bodies 10, after it has been applied within the space 11 and cured . The plate-shaped covers 50 are respectively coupled to the upper surface of an elastic body 10 of the upper part and the lower surface of an elastic body 10 of the lower part, by means of coupling 51. That is, the covers 50, having diameters corresponding to the diameters of the spaces formed by the central holes 11 of the elastic bodies 10, are respectively provided to the elastic body 10 of the highest part and to the elastic body 10 of the lower part of the bodies elastics stacked in the vertical direction, in order to seal and shield the containers 30 that store the nuclear waste in them. The covers 50 are fixed to the concrete 40 applied and cured in the spaces of the central holes 11 of the elastic body 10 of the highest part and the elastic body 10 of the lower part by a fixing means 51. For this, the covers 50 have a plurality of holes 53 from side to side, so that the covers are securely fixed to the concrete 40 by the fixing means 51. The fixing means 51 has a predetermined length, so that one end thereof is passed through the a hole 53 from side to side of the cover 50 and is combined with the hardened and cured cement, in the space defined by the central hole 11 of the elastic body 10 of the outermost part. The covers 50 are made of stainless steel in order to prevent oxidation by ground water or by sea water when the apparatus is installed on land or in the sea, and the fixing means 51 is made of the same material as the covers 50. According to this embodiment, the covers 50 have a plate shape, but are not limited thereto. For example, the cover 50 may comprise a top plate portion and a coupling plate portion projecting from the surface of the top plate and having the same diameter as the diameter of the space defined by the circular hole 11 of the elastic body 10, in order to increase the shielding and the sealing capacity between the covers and the outermost elastic bodies 10. The upper plate part has a diameter greater than that of the space 11 defined by the central hole 11 of the body elastic 10, so that the lower surface of the cover 50 comes into close contact with the upper surface of the elastic body 10, and the coupling part, which protrudes from the surface of the upper plate part is inserted into the space within the central hole 11, so that the covers 50 can be tightly coupled to the elastic bodies. According to this embodiment, the covers 50 are made of stainless steel, but can be made of synthetic resin or other materials, as long as these can prevent oxidation by terrestrial water or seawater. In addition, the outer surfaces of the elastic bodies 10 and the covers 50 are coated with a waterproofing agent, in order to increase the shielding and sealing ability of the containers 30 to store nuclear waste therein, and prevent the oxidation by terrestrial water or seawater when the apparatus is installed on land or at sea. The epoxy material is a water-proof agent 80, preferable. According to the embodiment of the present invention, the external surfaces of the elastic bodies 10 and the covers 50 are coated with epoxy material, but they can be coated with other materials as long as the materials can increase the shielding and the Sealing ability, and prevent oxidation by seawater. That is, the waterproof agent can be suitably selected from a variety of materials. Alternatively, the outer surfaces of the elastic bodies and the covers 50 can be coated with a layer of polyurea, which does not react with moisture, rarely cracks and is difficult to detach from a surface once it engages the surface, to which it has high elasticity, through a coating process, so that corrosion of the nuclear waste disposal apparatus 1 can be prevented because the germs can not penetrate into the nuclear waste disposal apparatus 1. Hereinafter, a method for manufacturing a nuclear waste disposal apparatus will be described in detail. Firstly, a plurality of elastic bodies 10 in the form of rings, each having a central hole 11, from side to side, is stacked at a predetermined height in the vertical direction (SI). When the ring-shaped elastic bodies 10 are stacked, a plurality of support bars made of wood is provided to the external surfaces of the elastic bodies 10, in order to maintain the straight vertical profile extending along the length of the body. the surface external of the elastic bodies 10, and to prevent the elastic bodies from collapsing. An internal space 11 is formed by the extension of the central holes 11 of the elastic bodies 10, and a plurality of containers 30 storing nuclear waste in them is stacked in the internal space 11. Then, a reinforced concrete 40 of high strength is injected into the internal space 11 to seal the containers 30 (S2). That is, after installing the containers 30 in the internal space 11 formed by the central holes 11 of the elastic bodies 10 stacked in the vertical direction, the reinforced concrete 40 of high resistance is applied around the containers 30 and in the internal space 11 of the elastic bodies 10 using a vehicle such as a ready mixed concrete truck, whereby the containers 30 storing the nuclear waste in them are shielded and completely sealed. In this case, since the concrete 40 is injected into the space 11 formed by the extension of the central holes 11 of the elastic bodies 10 and inside the respective empty internal spaces of the elastic bodies 10, the shielding and sealing effect is increased. According to the embodiment of the present invention, first the containers 30 that store waste Nuclear in these are installed in the space 11 formed by the extension of the central holes 11 of the elastic bodies 10, and then the concrete 40 is injected into the space 11 and cured, but the present invention is not limited thereto. That is, the sequence can change. For example, the reinforced concrete 40 may be injected into the space 11 of the elastic bodies 10 first, and then the containers 30 may be stacked in the space 11 before the concrete 40 is cured. In this case, the number of containers 30 stacked in space 11 is preferably three, but may also be less or more. The total height of the stacked elastic bodies 10 is preferably equal to the full height of the containers 30. Next, the injected concrete 40 is hardened and cured (S3). At this time, when the concrete 40 hardens and is cured, the coupling force between the concrete 40 and the elastic bodies 10 is increased due to the expansion of the concrete 40, the recovery force generated by the elasticity of the elastic bodies 10. surrounding the concrete 40, and the force of contraction in relation to the expansive force. Next, the covers 50 are coupled to the upper surface of the elastic body 10 of the further part. high and the lower surface of the elastic body 10 of the lower part, respectively (S4). In this case, the covers 50 are securely fixed to the concrete 40 by the fixing means 51 and the holes 50 from side to side, which are formed to penetrate the covers 50. The fixing means 51 engage with the holes 50. from side to side and are attached to the concrete 40. Next, the outer surfaces of the elastic stacked bodies 10 and the covers 50 are coated with a water-proof agent 80 (S15). Here, the water-proof agent 80 can be an epoxy. Thanks to the structure in which the outer surfaces of the elastic bodies 10 and the covers 50 are coated with a waterproof agent 80, the shielding and sealing ability of the nuclear waste disposal apparatus 1 is improved and can be prevented that the apparatus 1 is subjected to corrosion. In the nuclear waste disposal apparatus 1 having the above-described structure and manufactured by the method described above, the nuclear waste stored in the containers 30 is sealed primarily by the water-proof agent 80, secondly by the body thick elastic 10 and thirdly by reinforced concrete 40 high strength injected inside and cured in the elastic body 10. That is to say, the device has a triple shielding and sealing structure. Figure 4 is an exploded perspective view illustrating a nuclear waste disposal apparatus according to yet another embodiment of the present invention. The nuclear waste disposal apparatus according to another embodiment of the present invention is described with reference to Figure 4 and Figures 1 and 2. With reference to Figure 4, a plurality of elastic bodies 10 in the form of a ring is stacked to the vertical direction. At this time, a space 11 is formed by the central holes of the ring-shaped elastic bodies, in the center of the stacked elastic bodies 10. A plurality of containers 30, each storing nuclear waste therein, is placed in the space 11. In addition, a plurality of structural steel pieces 70 is provided in the space 11, between the inner circumferential edges of the elastic bodies 10 in shape of ring and the external surfaces of the containers 30. The structural steel pieces 70 have a ring shape and are installed in the vertical direction in the space formed by the central holes of the elastic bodies, between the internal surfaces of the elastic bodies 10 and the external surfaces of the containers 30. The structural steel pieces 70 installed between the inner surfaces of the elastic bodies 10 and the external surfaces of the containers 30 in the space 10, are combined with the concrete 40 hardened and cured therein, thereby increasing the ability to shield and seal the containers 30. In this case, the structural steel pieces 70 are first installed in the vertical direction in the space 11 formed in the central portions of the elastic bodies 10, the containers 30 are then stacked within the structural steel parts 70. , and the concrete 40 is applied to the containers 30, so that the concrete 70 is hardened and cured in the space 11 while being combined with the structural steel parts 70. The structural steel pieces 70 of suitable size to adjust to the space 11 at the point while it is being installed. Alternatively, the structural steel pieces 70 are prepared to have a predetermined size before installation. The structural steel pieces 70 preferably have a ring shape to provide space in a central portion thereof, to receive the container 30 that stores the nuclear waste in the space. According to the embodiment of the present invention, although the structural steel pieces 70 are first installed in the vertical direction in the space 11 formed in the central portions of the elastic bodies 10, the containers 30 are then stacked within the structural steel parts 70, and the concrete 40 is applied to the containers 30 in the space 11, the present invention is not limited thereto. That is, the present invention can be implemented in the following sequences: the structural steel pieces 70 are first installed in the vertical direction in the space 11 defined in the central portions of the elastic bodies 10, the containers 30 are then stacked within the structural steel parts 70, the structural steel parts 70 are installed in the horizontal direction in an upper end portion and a lower end portion of the vertically installed parts of structural steel 70, and then the concrete 40 is finally applied to the containers 30 inside the space 11. Figure 5 is a schematic perspective view illustrating a disposal apparatus for nuclear waste installed on land. With reference to figures 1, 2 or 4, the nuclear waste disposal apparatus 1 comprises a plurality of ring-shaped elastic bodies 10, stacked, reinforced concrete 40 of high strength applied inside and cured in a space provided in the central portions of the elastic bodies 10, the covers 50 provided on an upper surface of the elastic body of the upper part, and a lower surface of the elastic body of the lower part, respectively, a coated water-proof agent on the outer surfaces of the elastic bodies 10 and the covers 50, and structural steel pieces 70 installed in the space 10 provided in the central portions of the elastic bodies 10. With reference to figure 5, a plurality of nuclear waste disposal apparatuses 1, shown in figures 1, 2 or 4 are arranged on a layer of clay 10 meters below the surface of the earth. The nuclear waste disposal apparatus 1 is sealed by a mixture of clay and silt soil. The mixture of clay and silt whey is tamped and topped with general soil. In a plurality of nuclear waste disposal apparatuses 1, it is connected between them by a metal fixing means 90. That is, the elastic bodies 10 of the adjacent apparatus 1 can be tied by a rope. That is, after connecting the nuclear waste disposal apparatus 1 by a rope or a metal fixing means 90, the apparatuses 1 are accommodated on the floor.

The metal fixing means 90 is plated with titanium so as not to be corroded with terrestrial water. Since the plurality of nuclear waste disposal devices 1 is connected between them by the metallic fixing means 90 to have a predetermined height, this is able to withstand the natural disasters that may occur on land, and prevent the apparatuses 1 from being displaced from their designated installation positions. According to another embodiment of the present invention, the apparatuses 1 are installed on the clay layer 10 meters below the surface of the earth. Accordingly, if there is no geological clay layer at the selected nuclear waste disposal site, a layer of clay can be artificially formed at the nuclear waste disposal site, so that the apparatus 1 can be installed on the layer of nuclear waste. clay. Figure 6 is a schematic perspective view illustrating a nuclear waste disposal apparatus installed in the sea, and Figure 7 is a perspective view illustrating a group of nuclear waste disposal devices installed in the sea.

A plurality of the arrangement devices 1 of nuclear waste is connected to each other with a rope and discharged into the sea. That is, many apparatuses 1, each having containers 30 storing nuclear waste therein, are connected by a metallic fixing means 90, and then they are placed at a predetermined depth of water in the sea. At this time, the depth of the water determined to correspond to a position where the fish inhabit and lay their eggs. The apparatuses 1 are connected to one another by metal fixing means 90. The metal fastening means 90 are plated with titanium, so that they can not be corroded by seawater. Since the plurality of nuclear waste disposal apparatuses 1 are connected therebetween by the metallic fixing means 90 to have a predetermined weight, the apparatuses 1 are not easily displaced from their original installation position by the ocean current or by the condition of the ocean. According to the embodiment of the present invention, the apparatuses 1 are connected by the metal fixing means 90 plated with titanium but such connection can be made by a chain or other materials that are not corroded by the sea water. Here, the outer surfaces of the stacked elastic bodies and covers 50 are coated with a waterproofing agent 80 and then stone powder is preferably adhered thereto. The stone dust adhered to the outer surfaces of the elastic bodies and the covers covered with a waterproof agent provides the habitat fish and provides the seaweed with a place to grow, which generates an artificial colony of algae marine When the nuclear waste disposal apparatus 1 is discharged into the sea, the seawater can not permeate into the apparatus 1, and radiation from the container 30 is prevented.
